Danfoss ORF Orifice Assembly | Multi-Refrigerant | 067B2788
Product Description: The 067B2788 (Orifice No. 08) represents one of the higher capacity options in the ORF range, allowing for significant refrigerant flow in larger commercial evaporators. In the UAE’s evolving HVAC/R landscape, this orifice is particularly notable for its compatibility with R1234yf, in addition to standard refrigerants like R22, R404A, and the newer R448A/R449A blends. Whether it is for a large supermarket rack in Dubai or a specialized industrial chiller in Abu Dhabi, this orifice offers the flexibility to adapt to various cooling loads. The assembly includes a protective filter screen, ensuring that the high-precision orifice remains clear of system contaminants even in the most demanding Middle Eastern operating conditions.
Key Features & Benefits:
- Future-Proof Compatibility: Rated for a vast array of refrigerants, including R1234yf, R513A, R448A, and R449A, making it ideal for UAE’s sustainable cooling projects.
- Large Capacity Metering: Orifice No. 08 is designed for systems requiring higher mass flow rates without sacrificing precision.
- Integrated Filter Security: Comes with a built-in filter screen to prevent debris from damaging the valve seat, a vital feature for high-vibration UAE industrial sites.
- Modular Versatility: Allows for quick on-site capacity changes within the TUA/TUB/TQA valve series, reducing downtime for UAE facility managers.
- High Durability: Fabricated from premium materials to maintain accurate calibration despite the intense thermal cycling common in the UAE.
